چکیده
In the crystal structure of the title molecular salt, C(13)H(30)N(5)O(+)·C(24)H(20)B(-), discrete guanidinium cations and tetra-phenyl-borate anions are present. The C-N bond lengths in the CN(3) unit are 1.3427 (12), 1.3445 (12) and 1.3453 (13) Å, indicating double-bond character. The central C atom is surrounded in a nearly ideal trigonal-planar geometry by three N atoms and the positive charge is delocalized on the CN(3) plane. The bonds between the N atoms and the terminal C-methyl groups all have values close to a typical single bond [1.4595 (15)-1.4688 (12) Å]. In the crystal, cations are connected by C-H⋯O contacts generating a chain along the c axis.
